2. How does the Polygraph Work?
The physiological changes the Polygraph monitors on someone being tested are, blood pressure, sweat gland activity, blood flow, upper body movement. Usually the Polygraph Examiner will compare different reactions to formulated questions throughout multiple tests with responses from truthful and deceptive questions to analyse the charts to ascertain whether the subject was deceptive or truthful. The test results supplied at the end of the examination to the client in report format will include a result from the qualified examiner from Lie Detectors UK running a Lie Detector Test in Exeter.

There have been a few limited studies potentially showing a higher accuracy levels as some companies may quote.
4. How much does a Lie Detector Test cost in Devon?

5. What Questions do we use and why?
We prefer to initially discuss your case on the phone to make sure that a Polygraph Test is a suitable for your situation. The most accurate technique we run is a single issue test that comprises of three questions that are very similar on a single issue, this allows us to achieve maximum accuracy on a Polygraph Test. We stick to question’s based on fact, we don’t test on emotion or on intent. The Examiners of Lie Detectors UK in Exeter also have to consider the excuses someone my give if they fail a Polygraph Test in Devon.
6. Questioning Techniques Used In Lie Detector Tests
A subject will be asked three different types of questions during the Lie Detector Test in Devon by the Examiner. Lie Detectors UK use guidelines set for accuracy to create directed lie comparison, irrelevant and relevant questions that are suitable for each case. The Lie Detector Examiner will work with you to develop the most suitable relevant questions for the case and will ensure all parties are happy with them prior to running any tests.
7. Pre-test Interview
Prior to the Lie Detector Test starting in Exeter a pre-test interview will commence that can last up to an hour. Here the Examiner will fully discuss the case with the clients and explain more about the complete process and answer any questions from the clients. A very basic Polygraph Test will be run which shows the subject what it’s like to take a Polygraph Test in Devon. This also allows the Examiner to make minor changes if required in order to get better chart readings on the real tests. Then a full review of all questions will take place to ensure the subject fully understands each question and how to answer.
8. Data Collection and Chart Scoring in Devon
A minimum of three charts are run on each subject where the questions are repeated but in a slightly different order. An average of the charts is taken to achieve a result, the Lie Detector Examiner in Exeter will run full analysis on the data taken before giving a result which can be No Deception Indicated (Pass) or Deception Indicated (Fail) or an Inconclusive result which is very rare if the correct techniques are applied. The Lie Detector Test Results will be communicated both verbally and in a full three-page report that will be posted to your Devon home on request. At our head office we print the report so you can take a copy home.
9. What is the Minimum Age Limit For Anyone Taking A Polygraph Test and Can I Take a Lie Detector Test in Devon whilst Pregnant?
The minimum age we can test is 14, however if we are to test someone under the age of 18 we require full parental consent and would look to ensure the minor is mature for their years. We can test a lady who is pregnant, we just need to ensure the pregnancy is normal with no complications.
10. History and the Future of the Polygraph
A Scottish Surgeon called James McKenzie invented the Lie Detector test in 1906, he was a heart surgeon. The ability to store and measure the variations with increased heart beat and sweating was at the core of the instrument we now know as the Polygraph or Lie Detector. Many years later in 1921, John Larson, an American Police Officer developed a better and more accurate version of Polygraph instrument for forensic use. Then in 1925 Leonarde Keeler improved John Larson’s equipment by replacing the smoke paper with ink pens to make it more efficient.
Accurate Results From a Lie Detector Test in Exeter
Accuracy of a Lie Detector Test in Devon
Polygraph tests are proven to be as accurate as 95% when the right equipment, examiner and questions are used. When Lie Detectors UK run a Lie Detector Test in Exeter we would only use a single issue method to achieve the greatest accuracy available. Accuracy can be diminished by the wrong questions, an examiner who isn’t qualified, use of old equipment and an environment that isn’t suitable to test in.
Can My Nerves Make Me Guilty When I Am Not?
Absolutely not, this is a very common question that we are asked almost daily. A subject will be nervous from the start to the end of the test, we are looking at reactions to questions rather than someone’s nerves or anxiety. And quite frankly if nerves had an impact everyone would fail where we are seeing pass rates of around 80%. The Polygraph Examiner in Exeter will work with you to make this situation as easy and as comfortable as possible.
Control Question Test
Lie Detector’s UK Examiners in Devon use the Control Question Test as a physiological baseline. Control questions are asked to make correlations with relevant questions in order to ascertain if a subject is lying. A good Examiner will stick to the Directed Lie Approach when choosing the suitable questions for the test. All questions will be fully discussed with the examinee prior to taking a Devon Polygraph Test.
Lie Detector Alternatives
What Is Eye-tracking?
There is a screening tool that uses pupil dilation however it’s not as accurate as a Polygraph Test at 85% accuracy and requires the subject to have a good reading skills. Eye tracking for Lie Detection looks at small movements in the eye within the pupil to ascertain if the subject is being truthful to a series of questions.
Voice Stress Analysis
Functional magnetic resonance imaging machine shows the use of oxygen by the brain and highlights the parts of the brain using oxygen to determine whether a subject is telling a lie. Again results have shown this not to be very reliable.
Micro expressions or involuntary facial expressions are observed by a high speed camera. Micro expressions can be used to identify truthful or non-truthful behaviour. However again not reliable in the many case studies.
Truth drugs including Ethanol, Sodium Thiopental and Cannabis amongst various others have historically been used to obtain information from subjects without their consent. Whilst lots of drugs have been tested there is no one substance that works on all.
